What is Change Notifier?
Flutter's ChangeNotifier is a fundamental class for state management in Flutter. It allows developers to handle and notify listeners of data changes, ensuring efficient updates to the user interface. By extending ChangeNotifier, developers can create custom classes to represent specific states or data models. Integrating ChangeNotifier enhances the user experience by managing state and dynamically updating the UI. It simplifies state management and enables the creation of interactive Flutter applications.
